Hi all...
I went to the shop and hooked up everything from scratch, with the two legs of my 1ph 240 to L1/L2 (jumpered) and L3. I clipped and wire-nutted the neutral wire. I also ran a dedicated wire from the VFD ground to Earth ground. The 3ph motor is hooked up as previously stated (U,V & W plus ground).
I plugged the VFD in and... (drum roll) the breaker tripped again.
So unless anyone has any other thoughts, I suspect I cooked the VFD. I think I'll call Hitachi tomorrow, bare my soul, and see what can be done.
Thoughts???
Thanks again,
